[SOLVED] OpenGL video playback slow on radeonhd

Hi,

My video playback is very slow when using OpenGL output, both in VLC and mplayer.  When using the x11 driver, the playback is normal in VLC, but in mplayer there is a problem with the aspect: the picture does not scale.

I have a Radeon mobility X1600 and an up to date Arch64. glxinfo report direct rendering, and glxgears gives about 215 FPS at the default window size (if I make it smaller, then it boosts to about 700). I don't use fglrx, since I can't put the laptop in suspend to ram mode with it - rather, I can but then I can't wake it up

Any ideas?

Thanks!

Eduardo

If you are using the radeonhd maybe something isn't implemented yet, check here http://www.x.org/wiki/RadeonFeature maybe this will help you figure out the problem.

Hi,

Thanks for the link!

I realized that the offical Xorg ati driver also has support for my card. I just switched to it, and the mplayer problems are solved Incidentally, the glxgears count went up to about 1450. The suspend to ram also works, so I think I'll stick to this driver.

Thanks again!

Regards,

Eduardo
